Exactly. I'm not a programmer because I don't program. I can't play guitar because I don't play guitar. I can't speak another language because I don't practice one. It sounds obvious but doing the thing you want to do is critical to doing it.
It seems not to be entirely obvious to the students in my classroom. Today second day of the semester, job one is to explain that they need to have a notebook. They need to write in the notebook. And they need to do the homework in the notebook. They seem not to know that, many of them.
